Mystery is truth's dancing partner.

The best slave is the one who thinks he is free.

The hardest thing is to see what's under your very eyes.

Beauty is a manifestation of secret natural laws, which otherwise would have been hidden from us forever.

What makes people happy is activity; changing evil itself into good by power, working in a God like manner.

The dear good people don't know how long it takes to learn to read. I've been at it eighty years, and can't say yet that I've reached the goal.

It is impossible that beauty should ever distinctly appreciate itself.
